US Patent for Method for charging flowable explosives into

In the mining of underground ore bodies, boreholes for the explosive dislodgement of the ore are frequently drilled upward into the ore formation. These upwardly extending boreholes (up holes) are charged with explosives with great difficulty, especially in chambers having high ceilings.

General guidelines of Charging and Blasting in Hot Strata

Only slurry or emulsion explosives, preferably bulk explosives to be used for hot hole blasting purpose. It is preferred that explosives charging may be started near the initiation point first, (i.e., load explosives in the sequence in which the blast will be fired first).

Metal Mines Blasting slideshare

The type of explosives used ranges from free flowing bulk loaded ANFO in dry hole condition to high strength Emulsion explosives in wet hole condition. The charge factor / explosives consumption in this type of blasting is generally kept of the order of 0.1 to 0.25 kg / tonne of blasted ore.

Chapter 8 BLAST DESIGN National Park Service

resulting decrease in the diameter of the explosives column, reduces the amount of explosive energy within the borehole. The blaster must use higher energy explosives to balance the lost energy. Necessary explosive energy adjustments at the borehole can be made to compensate for excessive toe, hard bottom, or cap rock.

Mineral processing

A later example was the Cornish stamps, consisting of a series of iron hammers mounted in a vertical frame, raised by cams on the shaft of a waterwheel and falling onto the ore under gravity. The simplest method of separating ore from gangue consists of picking out the individual crystals of each.
